  1. Influence of the Load Duration on the Design Value of the Strength

    Load Combinations in Timber Structures for European and American Timber Standards

    In addition to determine loads, there are some particularities concerning the load combinatorics in timber design which have to be considered. Contrary to steel structures where the largest loading results from all unfavorable actions, in timber construction, the strength values are dependent on the load duration and the timber humidity. Special characteristics have to be considered as well for the serviceability limit state design. The following article discusses the effects on the design of wooden elements and how this is possible with RSTAB and RFEM.

  2. DSTV Library for Connections in RF-/LIMITS

    DSTV Library for Connections

    RF‑/LIMITS analyses the ultimate load capacity of timber and steel connections. The ultimate elastic capacity of joints according to DSTV has now been implemented in the add‑on module. The library has been extended to include the connection types IH, IS, IW, IG, IK and PM. The filter functions ensure a comfortable selection of the connections. If the designs are not fulfilled, you can determine an optimization function for the connection from the DSTV Library.

  3. Figure 01 - Checking Horizontal Deformations with RF-/LIMITS

    Checking Horizontal Deformations

    To control the lateral displacements of a model, you can use the RF-/LIMITS add‑on module. This add‑on module allows you to, for example, run a serviceability limit state analysis to find horizontal nodal deformations and to set it against a limit value.

    Modeling Cross-Laminated Timber Structures 6

    Usually, the lifting forces acting on a structure, which are mostly resulting from the wind loads or a dynamic analysis, are transferred into the ground through ties. In one of the previous posts, I already described this connection.

  5. Figure 01 - Dlubal RFEM 5 & RSTAB 8 - Comparing Results with Defined Limit by Using RF-/LIMITS

    Comparing Results with Defined Limit

    With the RF‑/LIMITS add‑on module, you can compare the load‑bearing capacity of members, member ends, nodes, nodal supports, and surfaces (only in RFEM) by means of a defined limit. Furthermore, you can check nodal displacements as well as the cross‑section dimensions.

    In this example, we want to compare the column footings of a carport with the maximum allowable forces given by the manufacturer.
